The dreaded ICE DAM. Our weather here in Whatcom County was the perfect breeding ground for an ice dam.
An ice dam is a ridge of ice that forms on a roof and prevents melting snow/ice (water) from draining off the roof. With nowhere else to go, and with freezing at night and melting during the day, the water will eventually back up behind the dam and ultimately leak into the home causing severe damage to roof shingles, ceilings, walls, insulation, and more. If damage from an ice dam goes unnoticed in an attic, there is also a potential for mold/mildew to form.
